BACKGROUND OF THE INVENTION

1. The Field of the Invention

The present invention is in the field of devices for supporting a selected object.

2. The Relevant Technology

When scrapbooking, many friends will often meet together, bringing their own materials and tools to work together (e.g., at a single kitchen table of one of the friends). Such an activity is known as a “crop”. In such an environment space is often very limited because of the number of people crammed around the table. Because of this, space is at a premium and there is a need to maximize use of the available space.

One tool routinely used by scrapbookers is an ATG tape gun, sold by Scotch (3M). The gun is marketed and sold as a picture framing tool (e.g., used to apply double sided sticky tape), although many enthusiasts within the scrapbooking field have recognized its value when used to apply double sided sticky tape when creating a scrapbook page. Besides its great utility in applying a length of double sided tape is the ability to salvage a broken role of tape. Tape dispensers marketed within the scrapbooking field (and directly intended for such use) simply do not allow salvage of a broken role of tape. The roll must be discarded and replaced with a new roll, which is wasteful. One disadvantage of using the ATG gun though, is its size and bulk. It is rather large, and takes up a large percentage of the space available to an individual scrapbooker attending such a gathering.

BRIEF SUMMARY OF THE PREFERRED EMBODIMENTS

The present invention relates to a self-leveling hook device for use in supporting an object (e.g., a gun shaped tape dispenser). In one embodiment, the hook includes a frame, means coupled to the frame for attaching the frame to a support surface (e.g., a table, countertop, wall, etc.), and a saddle including a pair of support arms coupled to the frame. The support arms are coupled to the frame at one end of each arm, and are selectively rotatable relative to the frame so as to be self-leveling. In addition, each arm is independently rotatable relative to the support frame and one another such that the arm ends opposite from where the arms are coupled to the frame may be moved apart from one another to provide a desired spacing so as to cradle and support an object having a width within a wide range.

In one embodiment (e.g., in which the frame is configured to clamp to a tabletop), the frame is generally C-shaped, including a first leg that is oriented substantially vertically (e.g., when coupled to a horizontal tabletop), a perpendicular foot extending from one end thereof, and a perpendicular bracket extending near an end opposite the foot. The foot and bracket are substantially parallel to one another. The bracket includes a threaded hole formed through the bracket for receiving a threaded stem of a compression knob assembly.

An exemplary compression knob assembly for attaching the frame to a support surface (e.g., a tabletop) includes a threaded stem, a compression knob at one end of the stem, and a compression disc at an opposite end of the stem. The stem is disposed through the hole of the frame bracket. In use, the compression knob can be rotated to adjust the distance between the foot and the compression disc so as to accommodate a given width of a table top, counter top, or other support surface to which the device is to be coupled.

In one embodiment, the spaced apart support arms include a first upper arm portion and a lower substantially horizontal platform arm portion. When viewed from the side, the upper arm portions are substantially parallel to the vertical leg of the frame, and the upper arm portions are coupled to the frame on a front side opposite from the bracket, foot, and compression knob assembly disposed on a back side. Such a configuration allows the bracket and foot back side of the frame to couple to the edge of a tabletop, allowing the support arms to hang off the edge of the table. A tape dispensing gun or other item can conveniently be supported tableside by such a configuration. For example, the handle of a T-shaped tape dispensing gun extends downward between the platform arm portions, while the upper dispensing portion of the tape dispenser gun rests on the platform arm portions, supporting it convenient for easy access by a user, and without using any of the limited table top space.

The support arms are advantageously able to freely rotate about their coupling point to the frame (e.g., by means of a compression fastener comprising a bolt, a knob, a washer, and a nut). The support arms may be rotated apart from one another about their coupling points at the upper arm portion to provide a desired spacing, and the compression fastener tightened to maintain the selected spacing and angle between the arms. In addition, because the arms are coupled to the frame so as to be rotatable about the frame, the arms form a saddle that is self-leveling, able to provide a level, horizontal support plane between the platform arms, even if the frame is coupled to a surface that is not horizontal (e.g., the frame may even be mounted to a vertical surface, such as a door).

The self-leveling platform hook is not limited to use as a device for supporting a tape dispenser adjacent a table top edge. For example, the hook may be used to support other objects. The described compression knob attachment means may be replaced with another attachment means. Such embodiments may be used as a self-leveling picture hook or as a tool holder that mounts to a peg board.

These and other advantages and features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS I. Introduction

The present invention relates to a self-leveling hook device for use in supporting an object. In one embodiment, the hook includes a frame, means coupled to the frame for attaching the frame to a support surface (e.g., a table, countertop, a wall, etc.), and a saddle including a pair of support arms coupled to the frame. The support arms are coupled to the frame at an upper end of each arm, and are selectively rotatable relative to the frame so as to be self-leveling. In addition, each arm is coupled at an upper portion thereof so as to be independently rotatable relative to the frame and one another such that a distance between the lower free ends may be varied so as to cradle and support an object of any width within the adjustable range.

II. Exemplary Self-Leveling Platform Hooks

FIGS. 1-7 illustrate an exemplary self-leveling platform hook 100 of the present invention. The hook includes a frame 102, a compression knob assembly 104 for attaching the frame to a table top or other support surface, and a saddle 106 comprising a pair of support arms 108 a and 108 b, respectively. Frame 102 is generally C-shaped, including a vertical leg 110, a foot member 112, and a bracket 114. Tapered foot member 112 extends laterally outward from one end of leg 110, and bracket 114 extends laterally outward in the same direction as foot 112, but is located near an opposite end of leg 110 so that foot 112 and bracket 114 are spaced apart and extend substantially parallel to one another. Bracket 114 includes a threaded through-hole 116 through which the compression knob assembly 104 is fitted.

Compression knob assembly 104 includes a threaded stem 118 with a knob 120 disposed at one end thereof. A compression disc 122 is disposed at an opposite end of the threaded stem 118, and stem 118 extends through hole 116 of bracket 114, so that knob 120 is disposed on a top side of bracket 114, while disc 122 is disposed on an opposite bottom side of bracket 114. The user is able to selectively rotate knob 120 so as to raise and lower disc 122, adjusting the distance between foot 112 and disc 122. This exemplary configuration of attachment means allows the user to adjust the distance between foot 112 and disc 122 to accommodate a variety of widths of a tabletop, countertop, or other support surface (e.g., a vertically oriented door).

Saddle 106 includes two support arms 108 a and 108 b, each of which is pivotally connected to an upper portion of frame member 110 by means of a fastener 124. Each support arm is generally L-shaped, including a upper arm portion 126 a, 126 b and a lower platform arm portion 128 a, 128 b. Platform portions 128 a, 128 b extend in a direction substantially perpendicular to first arm members 126 a, 126 b so as to define a generally horizontal support plane for supporting an object to be supported by hook 100. Portions 128 a, 128 b may further include a small lip or angled extension portion 129 a, 129 b, as shown to prevent a supported item from sliding out of saddle 106. Arms 108 a, 108 b may comprise metal (e.g., bent sheet metal) over which an elastomeric (e.g., rubber) cover 109 a, 109 b (FIG. 8) is provided.

As perhaps best seen in the exploded view of FIG. 8, each arm includes a through-hole 130 a, 130 b through an end of upper portions 126 a, 126 b opposite lower platform portions 128 a, 128 b. When assembled, holes 130 a and 130 b are aligned, and fastener 124 (e.g., including a threaded stem 132, a knob 134, washer 136, and a nut 138) couples arms 108 a and 108 b to frame member 110 of frame 102. Advantageously, arms 108 a and 108 b freely pivot about fastener 124, so as to be self-leveling. In addition, the arms are independently pivotable relative to one another, such that the distance between lower platform portions 128 a and 128 b can be adjusted by the user. For example, by loosening knob 134, the user can then adjust the spacing and angle of the arms as desired, and then retighten knob 134 to hold the spacing and angle. This allows adjustment of the spacing between platforms 128 a and 128 b so as to accommodate the width of any of various objects to be supported by hook 100.

FIG. 9 illustrates hook 100 clamped to a tabletop 150, for example, at a scrapbooking crop. Tape dispensing gun 155 is supported by platform members 128 a, 128 b. Tape gun 155 is generally T-shaped, including an upper dispensing portion 156, and an elongate handle 158 that extends downwardly from upper portion 156, extending from approximately the center of upper portion 156. Handle 158 extends through the space between lower platform portions 128 a, 128 b, while upper portion 156 rests on platform portions 128 a, 128 b.

A user is able to quickly and easily take gun-shaped tape dispenser 155 from holder 100 when desired for use, and replace it as shown in FIG. 9, so that the tape gun 155 occupies essentially none of the limited table space, while being table-side, ready for quick and easy access. In one embodiment, lower platform portions 128 a, 128 b may each comprise a magnetic material or be formed of a metal material subject to magnetic attraction (e.g., arms 128 a, 128 b may be formed of a iron containing metal material), and an associated magnetic or magnetically attractable material (e.g., iron containing) may be disposed on or within the upper dispensing portion of the tape dispenser 155. Such an embodiment advantageously stabilizes the tape gun 155 within the hook 100. For example, when upper portion 156 rests on platform portions 128 a, 128 b magnetic attraction between the platform portions and corresponding magnetic/magnetically attractable material in the dispenser results in steadying of tape dispensing gun 155, preventing accidental dislodgement. Preferably at least part of platform portions 128 a, 128 b are formed of a strongly magnetic material so that all that would be required is to place one or more small pieces of magnetically attractable pieces of metal within upper portion 156 of tape dispenser 155. Angled ends 129 a and 129 b further aid in preventing accidental dislodgement.

FIGS. 10A-10B illustrate an alternative application and embodiment 200 which is similar to hook 100, but in which the frame 202 and means for attaching the frame to a support surface 250 have been modified. Frame 202 includes a vertical leg 210, with one or more angled pegs 212 extending outwardly from frame 202, opposite the arms 208 a and 208 b. As seen in FIG. 10B, pegs 212 can be inserted within complementary holes 214 of a pegboard 250. Hook 200 is illustrated supporting a hammer 255, in which the head 256 is supported by platform portions 228 a, 228 b, and handle 258 extends downward between platform portions 228 a, 228 b. In an embodiment where platform portions 228 a, 228 b include a magnetic material, steel hammer head 256 will be more securely held in place, preventing accidental dislodgement.

FIGS. 11A-11B illustrate an alternative application and embodiment 300 which is similar to hook 100, but in which the frame 302 and means for attaching the frame to a support surface 350 have been modified. Frame 302 includes a vertical leg 310, while also including one or more nail mounting holes 312 through which nails may be driven into adjacent wall 350 (FIG. 11B), so as to support hook 300 on wall 350. Hook 300 is illustrated supporting a picture 355, in which the picture hanging wire 356 is supported by platform arms 328 a, 328 b. Because saddle 306 is self-leveling, there is no need to ensure that hook 300 is mounted level on wall 350, as is typically required with existing picture hanging devices. Under its own weight and that of picture 355, saddle 306 will automatically level itself under influence of gravity.
